If you don't show what you do then I cannot tell.  You don't include the 
wlan debug msgs that show the directed ProbeRequest frames so I cannot 
be sure they are going out.  If they are not sent then the ap will not 
respond.  If you set scan_ssid and you're not seeing the ProbeRequest 
frames then you'll need to figure out why.

This just means the beacon frame included an IE that was not handled. 
You appear to have to have enabled "elemid" debug msgs.
